PRINTER/S QUOIN.

Application filed November 28, 1922. serial No. 603,813.

To all whom it may concern:

Be it known that l, GEORGE DUNOANSON, J12, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Printers tuoin, oi which the following is a full,

o clear, and exact description.

The present invention relates to new and useful improvements in printers furniture, and it pertains more particularly to a printers uoin It is one of the objects of the invention to provide a new and improved printers quoin in which the elements constituting the quoin after they have been adjusted, may be locked in adjusted position.

With the above and other objects in view, reference is had to the accompanying drawings, in which- Figure 1 is a detail plan View showing the manner of use of the quoin;

Figure 2 is a detail sectional view taken on the line 22 of Fig. 1;

Fig. 3 is a detail sectional view taken on the line 33 of Fig. 1;

Fig. 4 is a perspective view of one of the elements of the quoin;

Fig. 5 is a detail perspective view of the other element of the quoin.

Referring more particularly to the drawings, the quoin comprises two members 5 and 6. Each of these members 5 and 6 has an enlarged end portion 7 and 8, respectively, and said enlarged end portions are provided with slots 9 and 10, respectively.

Tie member 5 of the quoin is provided with a flange or web 11, and said flange or web is slotted as indicated by the reference character 19 The member 6 of the quoin has a flange or web 13, such flange or web 13 being provided with a plurality of guide pins let which project therefrom as shown. Each flange of each member is ofl'set with respect to the lateral dimension of its respective member, and each flange when the members are placed together is adapted to be engaged in the slot of the enlarged portion of the opposite flange. By this construction it is apparent that the two members when secured together will form a quion, the side edges of which will at all times be parallel.

After the members have been placed together the guide pins let are positioned in the flange 13 in such a manner that they-project through the slot 12 of the flange 11, and thus form a means for preventing the two members from becoming detached one from the other.

Carried by the enlarged end portion 7 of the member 5, is a set screw 15, and carried by the enlarged end 8 of the member 6, is a set screw 16. The set screw of each member is adapted to engage the flange of the opposite member in such a manner that the two members will be prevented from longitudinal movement relative to each other when the set screws are turned up.

The device operates in the following ianner:

The quoin is positioned after it is turned up with a key in the ordinary manner: When this has been accomplished, either of the set screws 15 and 16 may be tightened until it exerts a binding action upon the flange of the member by which it is not carried. Upon turning up the set screw the two members are locked against accidental displacement or longitudinal movement with respect to each other, this insuring proper operation of the quoin.

From the foregoing it is apparent that the present invention provides a new and improved printers quoin, which after the same has been adjusted may be locked to retain its adjusted position.

What is claimed is:

A printers quoin comprising two interengaging wedge-shaped members. each of which is provided with an offset longitudinally-extending flange, an enlarged slotted head portion formed on one end of each of said members, the slotted head portion of each member being adapted to receive the flange of the opposite member, a longitudinal slot formed in the flange of one of the members, guide elements carried by the flange of the other member, said guide elements being adapted for reception within the longitudinal slot of the other member, and means carried in the enlarged head portion of each member and adapted to engage the flange of the opposite member to prevent relative movement of the members, said means comprising set screws.
